VISION ATTACHMENT l Filed Feb. 21, 1927 Patented Apr. 15, 1930 lTED.STATES "ATEN vision arracnmmv'r Application ma retmr at, as. Serial no.leases.

This invention relates to improvement in vision facilitation andenlargement attachments for vehicles, and has' as its primary objectfacilitating the easy observationflby y the operator of a vehicle ofconditions other- Wise obscure or difficult to see.

A more detailed object is thedisclosure to the operator of the vehicle,vWithout necessitating alteration in his position, of the factsregarding si nal lights or other signal condi-- tions, even w en such sinal apparatus is out of the ordinary range of observation as whenlocated above and too near the vehiiile to beseen by the operator.

With thcseand further objects in view, the invention comprises areflector located and contoured to afiord a wide range of observationincluding Wide angularity thereof. The invention also comprisescertain'other novel constructions, combinations, and arrangements ofparts as will be hereinafter specified and claimed.

In the accompanying drawing--- Fig. l is a fragmentary erspective viewat on a reduced scale of a vehic e equipped with an embodiment of thepresent invention Fig. 2 is an enlar ed, detailed, edge view of anembodiment o the invention, a part of the vehicle being indicated insection so Fig. 3 is an inverted plan thereof.

Referring to the drawing by numerals, it indicates a bracket anchored tothe Wall 2 of an automobile or other vehicle 3.. The

Wall 2 is preferably some partofthe auto-' mobile body adjacent to theseat of the opera tor or driver, and may be a part of the entrance dooror one of the front uprights for the Windshield or otherwise, it belngof primary importance that the present improved attachment be properlylocated both for the observation by the vehicle operator and forassuming the required angular relation. to the area to be envisioned.Pivotally engaging the outstanding arm of the bracket 1 is angle orapproximately at right angle to that portion of itself which projectsthrough the outstanding arm. of the bracket 1. The part of the arm 4which extends through the I bracket 1 is preferably threaded and pr0- arod 4, which is preferably extended at right '4; is a reflecting device6 having a convex reflecting surface adapted to be so located as toenvision a maximum area from a given point of observation. The contourof the reflecting surface 6 is such thatv the periscopic observationafforded is comparable vvith image thrown by a Wide angle lens, so thatby proper adjustment of reflecting surfaee 6 (the adjustment having oncebeen determined remains substantially constant) the driver or operatorof the vehicle can readily see signal light conditions, even though suchlights may be almost immediately overhead or considerably at one side orsubstantially in advance, and observation may be made Without any changeWhatever in the position or posture of the operator. The manner of themounting of the rodeo tor 6 and the character of the material of suchreflector are susceptible oil very substantial variations. As a matterof expediency, con venience and inezrpensiveness of construction,

the said refiector'may be a mirror produced on a lens-like casting ofglass and the reflector is preferably marginally circular as seen at 'lin Fig. 3.. The body of the reflector 6 may be engaged for adjustableconnection to rod 41- by various forms of apparatus, one of Whichconsists of an adjustable tripod of triangular plate sections seen bestin the inverted plan in 3a The said plate sections preferably consist ofa main plate section 8 and a supplemental plate section 9. The terminalpoints or angles oi? the plate sections 8 and. 9 out" standing beyondthe circular marginal. pot tion 7 are folded about the marginal portionto provide clamping tabs it. Each of the plate sections 8 and 9 isprovided with down. vvardly bent or extended eyes it) snugly surrounding the rod 4-. Plate section 8 is probably provided with tvvo ofthe eyes 10 While plate section 9 may be provided only with a singleeye. The rod 4, near its outerend, is termed with an annular shoulder11, and

from the shoulder 11 to its outer end the rod is tilt till

threaded and the threaded portion engaged by a nut 12. The eye 10 of theplate 9 and the outer eye 10 of the late 8 are of slightly less diameterthan the diameter of the main body 5 of rod 4, so as to be susceptibleof being clamped by the nut 12 against the shoulder 11.. A lockin washer13 is preferably disposed between t me said last named eyes 10, so that,

when the nut 12 is threaded tightly against m the eye 10 of the plate 9,the plates 8 and 9 are thereby firmly clamped in the given position onthe rod 4. The nut 12 may be left sufliciently loose to allow thereflector 6 and 7 plates 8 and 9 to be rotated about the rod 4: 15 undersubstantial, frictional resistance, so that the reflector 6 may beadjusted angularly and vertically to the exact location best adapted to theneeds of the driver for disclosing such area as he desires to observe.29 Obviously adjustment of rod 4 about its pivotal engagement withbracket linay be hkewise accomplished. V v The use of the instrumentwill be readily understood without detailed description, and

:5 consists generally of the mere observation of I the mirror by theoperator at such times as he uires information of signal conditions or 0er matter not within his easy and ready range directly in advance ofhim. v

" so What is claimed is- A vision facilitating attachment for vehiclecomprisin a reflector, plates having tabs clamping t 1e reflector,'s'a1dplatw having upstan ing eyes, a sup rting rod extending 86 through saideyes an having ashoulder en- Y gaging one of the eyes, means for'clampinthe plates together and to the rod against sai shoulder for retainingthe reflector on the rod and one of said plates being provided I o witha supplemental eye embracing said rod. In testimon whereof I aflix my siature.
